Collection of Covolution Interpretation Examples Examples of Covolution
Covolution is the process by which information objects expand and refine their possibility-spaces through computation, prediction, and design. It differs from classical Darwinian evolution not by replacing it but by adding a layer: where evolution operates through variation and selection on pre-existing possibility-spaces, covolution operates through the active construction of new possibility-spaces by information objects capable of modeling their environments.
This page presents examples illustrating covolution at increasing levels of computational sophistication, beginning with cases that overlap heavily with classical evolution and ending with cases where covolutionary processes dominate. Each example is presented in the same structure: what the information objects are, what they construct, and what role computation and prediction play in the construction.
Molecular optimization and selection
Information objects involved: Individual molecules within cellular metabolic networks; regulatory proteins.
What is constructed: Refined biochemical pathways that respond to environmental conditions with progressively higher specificity.
Role of computation: Minimal but real. Regulatory feedback loops, allosteric responses, and signal transduction cascades compute relationships between input concentrations and output responses. The selection that refines these pathways across generations is largely Darwinian, but the within-generation operation of the pathways themselves involves continuous information processing.
This is covolution at its boundary with evolution. The line between them is not sharp at this level.
Bacterial CRISPR-Cas adaptive immunity
Information objects involved: Bacterial cells equipped with CRISPR-Cas systems.
What is constructed: A heritable, sequence-specific memory of past viral infections that can be transmitted to descendants.
Role of computation: Substantial. The CRISPR-Cas system captures fragments of viral genomes, stores them in the bacterial chromosome, and uses them to recognize and cleave future invasions of the same virus. The system therefore encodes environmental experience into heritable genetic information through a directed, computational mechanism — not through random mutation followed by selection.
This is a clear case where evolution alone is insufficient to describe what is happening. Classical evolution operates on random variation; CRISPR-Cas operates on captured environmental information. The bacterial population is constructing its own future possibility-space by recording its past encounters.
Beaver dam construction
Information objects involved: Beavers as individual organisms and as family groups.
What is constructed: Physical dam structures that transform local hydrology, creating wetlands that beavers and many other species depend on.
Role of computation: Substantial. The beaver's behavior in selecting dam sites, choosing materials, and adjusting construction in response to water flow involves real-time computation. Dam construction is not a fixed action pattern; it is an adaptive response to specific environmental conditions.
The genetic basis for dam-building capacity arose through Darwinian evolution. But the actual construction of any particular dam is a covolutionary act. The beaver is computing the local environment, predicting how water will flow, and modifying the landscape to construct a niche that improves its own fitness and the fitness of its descendants. The dam, once built, becomes part of the symvironment that future beavers inherit.
This is the classical case of niche construction in the biological literature (Odling-Smee, Laland, and others). Covolution generalizes the niche-construction insight: beavers are not the only organisms that construct their possibility-spaces, and dam-building is one instance of a broader pattern.
Sexual reproduction as predictive recombination
Information objects involved: Sexually reproducing individuals; mating pairs; populations within which mate choice operates.
What is constructed: Offspring genomes that combine parental information in ways no asexual reproductive process could produce.
Role of computation: Indirect but real. Mate choice in species with mate selection involves computation — assessment of partner quality, prediction of offspring viability, evaluation of compatibility. The recombination of genomes during meiosis is itself not random in the strict sense; it is structured by chromosomal architecture and recombination hotspots that reflect prior evolutionary refinement.
The result is a generation of offspring whose genetic composition is partly the product of computational decisions by parents and partly the product of structured recombination mechanisms. Neither part is well described as pure random variation followed by selection. Both involve predictive elements about which combinations are likely to succeed in the offspring generation.
Domestication
Information objects involved: Human populations and the species they domesticate (plants, animals, microorganisms).
What is constructed: New biological lineages whose properties are shaped by the predictive activities of the domesticating species.
Role of computation: Central. Domestication is the deliberate selection by one species of traits in another species, based on predicted utility. Wheat did not become high-yielding through environmental selection alone; it became high-yielding because humans selected for high-yielding variants generation after generation, based on their judgment about which traits would be valuable.
Domestication is covolution between two species. The human population computes the desired traits; the domesticated population evolves toward those traits under directed selection. Both species are transformed by the process. The relationship is not parasitic or symbiotic in the classical sense; it is a covolutionary partnership in which one partner is doing most of the computation.
Large-scale infrastructure construction
Information objects involved: Human civilizations as social information objects; engineering institutions; planning organizations.
What is constructed: Infrastructure of substantial size and durability — canals, dams, transportation networks, communication systems, urban environments.
Role of computation: Dominant. The Grand Canal of China, constructed over more than a millennium, is an example. Its construction required planning, engineering calculation, political coordination, resource allocation, and predictive modeling of future use. No purely evolutionary process could have produced it, because the construction depended on information transmission across generations through means — written language, accumulated technical knowledge, institutional memory — that biological evolution does not provide.
This is covolution at the civilizational scale. The information objects doing the work are not individual organisms but social and technological horons: organizations, traditions, accumulated bodies of knowledge. The fact that biological organisms (humans) are involved does not make this biological evolution. It makes it covolution operating through biological substrates that have themselves been shaped by prior covolution.
The contrast with classical evolution is sharp. Evolution could not produce a canal-building species in any realistic timeframe, because canal construction requires symbolic communication, accumulated technical knowledge, and large-scale coordination — capacities that arise from cultural and institutional covolution rather than from biological evolution alone.
Species synthesis and horizontal gene transfer
Information objects involved: Microbial populations, especially bacteria and archaea; certain plant and animal lineages.
What is constructed: New species or strains formed not through gradual descent with modification but through the combination of genetic material from multiple lineages.
Role of computation: Variable. Horizontal gene transfer in bacteria is largely opportunistic but is regulated by computational mechanisms (the CRISPR-Cas system again, restriction enzymes, plasmid management). Hybridization in plants and animals involves both chance and selection. Engineered hybrids and laboratory-constructed organisms involve substantial computation by the species doing the engineering.
This example matters because it shows that Darwin's principle of gradual descent with modification is not the only mechanism by which biological diversity arises. Sometimes lineages combine rather than diverge. Sometimes genetic information jumps between lineages. Covolution accommodates these phenomena naturally; classical evolutionary theory has had to be expanded substantially to do so.
What these examples share
Reading across the examples, several features of covolution become visible.
In every case, the information objects involved do more than vary and undergo selection. They process information about their environments, model possible futures, and act to shape which futures occur. This processing happens at every scale, from molecular regulation to civilizational planning.
In every case, the result is the construction or transformation of possibility-space. The beaver does not simply occupy its environment; it modifies the environment, creating possibility-spaces that did not exist before. The CRISPR-Cas system does not simply respond to viruses; it constructs a heritable memory that changes what future infections will mean for the bacterial lineage. The engineering institution does not simply build a canal; it constructs the social, technological, and physical possibility-space within which future construction projects become feasible.
In every case, computation matters at the scale of the action. Even where the underlying capacity arose through Darwinian evolution, the actual exercise of that capacity in any particular instance involves real-time information processing, prediction, and adjustment. Covolution is not a replacement for evolution. It is the active, computational layer that operates on top of evolutionary capacity to produce specific outcomes.
What these examples do not share
The examples differ substantially in how much covolution operates relative to classical evolution. Molecular optimization is mostly evolution with a thin covolutionary layer. Beaver dam construction involves substantial covolution by individual organisms but is constrained by evolved capacities. Civilizational infrastructure construction is overwhelmingly covolutionary, with evolved biological capacities serving as substrate rather than as the primary engine.
This variation is not a problem for the framework. Covolution exists on a spectrum. Some processes are nearly pure evolution; some are nearly pure covolution; most lie somewhere between. The framework's value lies in giving us a vocabulary for the differences along this spectrum, not in claiming that all biological processes are equally covolutionary.
